In the typical veneer contracts you have seen, is the final board feet calculated based on the heart wood diameter or does it include the outer diameter of the tree including bark and sap wood? When the tree is alive you can only measure the outer diameter to get a board feet estimate, but could I guess at a typical bark and sap wood amount to adjust for that. Or does the Doyle log scale take bark and/or sapwood dimensions into account already? My end goal here is roughly estimating a live tree's veneer board ft.
